Just two months after the Port of Virginia’s container volumes broke their all-time high, they did it again — the latest sign that cargo diversions from a still-recovering U.S. West Coast may have more staying power than originally imagined.

The Port of Virginia is falling short. Record volumes and a return to profit in the past year have been matched with near-unprecedented congestion and user dissatisfaction, Port Director and CEO John Reinhart said Thursday.

While besuited port industry executives milled about hotel ballrooms at the Virginia International Trade Symposium Thursday, truck-driving men and women in shirtsleeves marched in protest on the streets outside.

The Port of Virginia reported March volume of 229,410 20-foot-equivalent units — an increase of 16 percent year-over-year, and a port monthly record — but the increased volume has strained operations at Hampton Roads terminals.
